A convicted sex offender who went to a Round Lake Park school looking for his daughter pleaded guilty to a reduced charge Friday.

Gillermo Contreras, 45, was placed on probation for one year after pleading guilty to misdemeanor unlawful presence on school property.

Contreras, of 408 Kenwood Drive, Round Lake Park, was arrested Nov. 6 when he went to Murphy Elementary School because he said he believed his daughter missed the bus.

He is not allowed to be at any school because he was convicted in 2001 of aggravated criminal sexual abuse of a child.

His daughter, who does not live with Contreras, attends a different school and had not missed her bus on the day her father went looking for her.

Contreras was originally charged with a felony violation of the state sex offender registration law, but Lake County Assistant State's Attorney Ari Fisz agreed to reduce the charge in exchange for the guilty plea.
